O Lord, you are truly the Star that rises out of Jacob,
and the scepter that rises out of Israel.
In a new star you showed yourself as God,
and lying in the manger you showed yourself as God and Man,
so we confess you to be the one Christ.
In your great mercy grant us the grace of seeing you,
and show us the brightness of your light,
that all the darkness of our sins may be driven away.
Even as we long to see you,
refresh us with the joy of seeing you in your holy Word.

“the Star that rises out of Jacob, and the scepter that rises from Israel” is a reference to Numbers 24:17
“Even as we long to see you” the original source has “that so we who now languish with the desire of seeing thee, may be refreshed with the enjoyment of that blissful vision.” Alteration was made with the Epiphany hymn in mind, “Grant us grace to see you, Lord, mirrored in your holy Word.”
